Aftermarket fuel pump cause a 95 LT1 to gas out? Got a 95 lt1 that was in need of a serious tune up. Car in sig. I sent te computer out to be tuned (PCMFORLESS) because it was getting gassed out (on factory injectors) (had a tune on it previously as well) I gave PCmforless the specs on everything including the new injectors which actually flow 32 lb/hr with the 43.5 psi the fuel system feeds it. (those are factory calculated numbers. I have not tested my car. But it just hit me that the car had an aftermarket fuel pump when I bought it. So, my question is would that fuel pump cause above desired PSI and cause the injectors to flow too much gas in? Or will the FPR compensate for that? Or sould I get in touch with PCMforless with a recalculated flow number for injectors with fuel pump factored in. I'd have to pull it from the tank to know what it is. I'm not the one who put it in and neither was the previous owner.
